The answer is two double bonds
If they’re separated by only one single bond there said to be contracted
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
The Answer is A.) Carbon dioxide
Cause it is produced as a waste product during respiration in the cells of the body tissues, diffuses into the blood.
Answer: Option D.
Explanation:
Active transport is defined as the movement of solutes or molecules across a membrane on the basis of difference in solute concentration.
Active transport functions continuously due to diffusion that allows solutes to move constantly across the membrane. Cells have low concentrations of sodium (Na+) and high concentrations of potassium (K+). Hence, the electrical gradient and concentration gradient of sodium (Na+) that allows diffusion of the ion into the cell, and the electrical gradient of Na+ (a positive ion) that allows movement of ion inward to the negatively charged interior.
Hence, the correct option is D.
